This was actually a misunderstanding by Li Er. Horseshoe is not what he thought. Everyone in the world knew about it.

In ancient times, due to inconvenience in communication and information, the horseshoe did not attract attention after the appearance of the horseshoe, but was only controlled by some folk blacksmiths on a small scale.

No one cared about these blacksmiths, either because of lack of knowledge or because of their own treasures, took this simple iron piece to heart, while those with knowledge and culture were simply disdainful of studying such strange tricks and tricks.

With the addition of the two, if Li Hao had not mentioned Li Er by chance, I was afraid that it would have been many years before horseshoe would have become popular.

...

...

A quarter of an hour later.

"Those few small things?" Li Er said in surprise, holding the horseshoe presented by Feng Xi.

"Yes, your majesty, as long as you nail this object to the horse's hooves, you can greatly reduce the wear of the horse's hooves." With Lao Feng, Li Hao naturally did not need to explain harder. This general was in charge of the master's command to nail the horse's hooves that had just cooled down to Li Er's horse while solving Li Er's doubts.

"Well, let's see, let's talk about it." Li Er looked at the busy people and didn't seem to believe Lao Feng's words, but because the horseshoe had not been nailed yet, he could only wait patiently.

After a while, Li Er seemed to think of something, and called Li Chengqian and Li Hao and asked, "By the way, you two guys are here to find me, but what's the matter?"

Li Chengqian glanced at Li Hao, straightened his chest, and plucked up his courage: "Father, my son and Li Dejian were about to do surveillance today, and suddenly discovered something and wanted to report it to you."

"Let me tell me." Li Er narrowed his eyes, not knowing what he was thinking.

"During the inspection, my father, I found that when I was going to be a surveillance, there was no unified standard for me to make objects. Everyone was doing their own things, and when I was creating objects, they would do whatever I wanted, all my preferences. Therefore, I wanted to ask my father to formulate a national policy and unify the standards for making objects, starting with the surveillance, and implement standardized and modular operations."

Facing his old man, Comrade Li always felt a sense of terrifying oppression, fearing that he would be punished if he said it wrong. After finishing what Li Hao told him in one breath, he immediately looked at Li Er nervously, with fifteen buckets in his heart.

After hearing his son's words, Li Er first glanced at Li Hao and asked, "Is this what you think?"

"Uh..." Li Chengqian hesitated for a moment and wanted to turn around, but was pushed by Li Hao without any trace. He could only say with a stern voice: "Yes, my father, my son thought that if you want to do a good job, you must first sharpen your tools. If I want to be strong in the Tang Dynasty, I must follow the pre-Qin period and formulate more complete unified standards, rather than being satisfied with the status quo."

Regardless of whether Li Chengqian was right or wrong, at least his starting point was good. Li Er nodded in approval and continued to ask: "Explain standardization and modularization, I want to hear it."

"No." Without being scolded by the old man, Li Chengqian suddenly felt energetic and coughed dryly: "Standardization, modularity, as the name suggests, is to set a perfect standard.

Take the most popular bicycles at the moment as an example. To implement unified standards and regard all parts as standard modules after another, the advantage is to increase the proficiency of craftsmen. After all, the size and material are unified. If you create more, you will naturally become proficient. After being proficient, the speed of creation will naturally increase a lot.

Secondly, unified parts can be interchanged. If a part of a car breaks, it can be removed from other cars and replaced, or simply produce a bunch of such parts. Then, take out one and replace it and use it again. This can save resources and be convenient and fast.

The same method can also be used on the arms of our Tang Dynasty, such as crossbows, catapults, chariots, and tower cars. These are essential and easy-to-damage equipment on the battlefield. In the past, these arms would not be used if they were broken. If we carried out standardization and modular operations, we could completely piece together a few broken equipment or several units intact and put them into the battlefield."

Li Chengqian became more and more fluent in his speech, and in the end he even spitted out his saliva.

However, Li Er didn't care. His attention was completely attracted by Li Chengqian's words, "Reorganize broken equipment into one or several complete equipment."

As a horse emperor, Li Er, who had fought for the Tang Dynasty for many years, knew very well what this meant.

After the war, all the equipment was damaged. Just when the enemy thought there was a chance to leave, if several catapults and crossbows suddenly appeared, the attack on the enemy's anger could definitely be called destruction.

After realizing the benefits of standardization and modularity, Li Er slid his hands and laughed: "Okay, okay, the prince's proposal is very good, so let me leave this matter to you."

"Thank you, my son, I will live up to your high expectations." Li Chengqian, who was rare to be scolded, smiled with his eyes and knocked his head to the ground. Uh no, a big thousand... Uh no, it was not right. In short, he gave Li Er a bow.

Li Hao, who was standing aside, was also happy for Li Chengqian. At least he had been in contact with this kid for a while. From a relationship point of view, he still hoped that this kid could inherit the throne.

Of course, this does not rule out that he is now related to Li Chengqian being a grasshopper on the same rope.

"Li Dejian." Li Er suddenly turned his gaze to Li Hao again.

Li Hao hurried forward: "I'm here!"

"Assist the prince well, I always remember your kindness and will not treat you badly in the future."

What does Li Er mean? How did I do it? I feel like a relative.

Li Hao thought confused and answered honestly: "No!"

Li Er, who was in a good mood, waved his hand: "Okay, the horseshoe has been prepared. I want to go and see, you two should do whatever you should do."

Hey? What does it mean? Just kill the donkey?

What about the rewards that promised? What about the rewards that promised promised would not be unfair to me?

If it weren't for me, your horse's hooves would be ruined.

Li Hao looked speechlessly at the excited Li Er riding a tall horse he brought with him, and then silently watched Li Er disappear outside the door where he was about to be the prison. He was completely in a state of discomfort.

However, before Li Chengqian came to his senses from the excitement just now, he saw the old man leaving, and pulled Li Hao and said, "It's so good, Dejian, my father has been fooled. What kind of tricycle should we get next?"

Have you fooled it?

This father and son were sent by God to torture me.
